  1. 21. Dynamical aspects of atmospheric data assimilation in the tropics

    Författare :Nedjeljka Žagar; Erland Källén; Nils Gustafsson; Eugenia Kalnay; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tropical data assimilation; variational methods; mass-wind coupling; Meteorology; Meteorologi;

    Sammanfattning : A faithful depiction of the tropical atmosphere requires three-dimensional sets of observations. Despite the increasing amount of observations presently available, these will hardly ever encompass the entire atmosphere and, in addition, observations have errors. Additional (background) information will always be required to complete the picture. LÄS MER

  2. 22. Data-Driven Classification in Road Networks

    Författare :Oliver Stromann; Zahra Gharaee; Alireza Razavi; Michael Felsberg; John Folkesson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Connected and autonomous vehicles (CAVs) are an emerging trend in the transport sector and their impact on transportation, the economy, society and the environment will be tremendous. Much like the automobile shaped the way humans travelled, lived and worked during the 20th century, CAVs have yet again the potential to affect and reform all of these areas. LÄS MER

    Sammanfattning : This dissertation is a thematic presentation of the academic world, of Academia. The work on it has neither been directed by any specific research problem and research plan, nor structured by any established research method. LÄS MER

  4. 24. Coordinated MultiPoint Transmission with Incomplete Information

    Författare :Tilak Rajesh Lakshmana; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduling; precoding; coordinated multipoint; joint transmission; backhauling; particle swarm optimization; decentralized; stochastic optimization; convex optimization; efficient backhauling; centralized;

    Sammanfattning : The demand for higher data rates and efficient use of various resources has been an unquenchable thirst across different generations of cellular systems, and it continues to be so. Aggressive reuse of frequency resources in cellular systems gives rise to intercell interference which severely affects the data rate of users at the cell-edge. LÄS MER

  5. 25. Upper Secondary Teachers as Designers of Technology Use for Learning

    Författare :Elisabeth Rolf; Robert Ramberg; Ola Knutsson; Åke Walldius; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Design patterns; design for learning; digital competence; pedagogy; technology in education; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : The use of technology in education is by policymakers expected to expand, and efforts are laid out by the research community to support such a development. This thesis will explore how the introduction of design patterns in upper secondary education may contribute to an extended use of technology by applying the Educational Design Research (EDR) methodology.
